Hi All
Long time reader here in Aus, thought I�d join in.

Big thanks to Phill, I�ve read many informative write ups of yours now, hats off and thank you for your time and effort.

Several of us downunder (hi Laurie) have been talking of this for a while now, on AULRO and private chats, and it�s good to see another conversation started, I suppose it takes someone like Phill to attack the mechanical aspect in detail.

With my limited Auto Trans knowledge I have a Q for Phill (and others). The TDV6 D3 was 440nm, 3.0 TDV6 D4 600nm with higher rpm than the TDv8, my tuned TD6 is approximately 500-510nm. Does this bring the possibility of using a D3/4 box & TC in to equation given the engine outputs would be closer?

Regarding the electrical issues, doesn't the box simply need told the correct values over a can-bus connection and could that not be done by a custom interface device ? 3

Hi Harlie, good to see you here. Hopefully with everyone's thoughts, input and experience, someone will get this to work.

Cheers - Gav.

Good to see you here also Harlie !

Or better still why not get a box from a later model M57 equipped BMW ? This should sort out the flexplate and stater motor issues. I won't pretend to know the electronics like Harlie or SteveMFr , but could we get a CAN translation module setup from one of these autos, to use in the integration of the box into the Rangie ? Could this module be used on a 2006 Vogue Td6 update model ?
As there would be no need for an adaptor plate, this would leave the 30mm that Phil mentioned at the back of the box. If possible why not an adaptor plate to mount the DD295 transfer case in it�s original position ? This would require a custom output shaft, JPAT http://www.jpat.co.uk/5L40E%20Shafts.pdf
already do a custom HD shaft for the 5L40E, why not one for the 6HP26, they already have shaft diameter, splines loaded on their CNC machines, the rear annulus gear will have to be setup though. I�m sure they would sell more of these if it becomes a viable option !
If I was to go down this road, I would do a heavy duty rebuild of the auto with a custom billet torque converter, I still believe after much research that the T/C is the weak-link in this setup.
Jeremy Fearn�s big HP conversion is starting to look good again !!!
Again thanks to Phil for his expertise and the photos of the 5L40E and the 6HP26 compared to each other that made this reply possible.
Just my thoughts
Laurie

fantastic thread!

Here here!

Sorry Steve for the next bit : The Faultmate allows to search per ECU, however since you buy a license per VIN and model or a multiple VIN license per model, it would be costly to get enough licenses to get all the modules working. But I expect, once you have done that you could theoretically see all the ECUs, provided there are no different comms protocols running or the "translation module" screws that up. However that wouldn't make sense as if the comms protocols don't work the whole won't work.

Now Steve of course knows his kit better so he can maybe comment on the IID being able to get around communicating with the various ECUs even if they were originally from another car.

Now the way I understand it, the transmission, at least the ZF 6HP26 also has a ECU in the gearbox, in addition to the one under the hood/bonnet (in the big plastic box with the engine management ECU). Not sure if that provides any additional issues with interfacing and control.

Now I'm just a mechanical engineer and not a bits and bytes person so my knowledge in this area is far more limited then Harlie and Steve.

I do know that the JLR and ZF engineers spend many many hours tuning the software of the ECUs to get the best performance and I wonder if combining components that were not designed to work together will actually result in something desirable for us as drivers.

I do understand the challenge and fun in getting something that wasn't done before and make it work and from that perspective I hope you guys get the FrankenGear to work  MY 2010 5.0 SC Galway green and sand interior!!
Have the Faultmate MSV2 Extreme to be tinkering with the settings etc. !!
